The Saratoga County Sewer District will be doing as much as $500,000 in emergency repairs after a section of the main trunk line just outside Ballston Spa started to collapse.
The funding won’t be authorized by the county Board of Supervisors until Tuesday, but repair work on a 700-foot section north of Oak Street is already under way. That follows an incident in mid-March.
“The top of the line eroded and collapsed,” said sewer district Executive Director Chad Cooke.
Investigation determined that as much as 700 feet of the line — in an area that has already had problems due to aging pipes — was at risk.
“It hasn’t collapsed yet, but it looks a little the worse for the wear,” Cooke said.
The reinforced concrete line carries millions of gallons of sewage generated daily in Saratoga Springs and points north to the county sewage treatment plant in Halfmoon. It was installed in the mid-1970s, and now suffers from age-related corrosion.
The district has been repairing the line as needed by installing a fiberglass liner inside the pipe, and a contractor already doing that kind of work on a nearby section of pipe is performing the emergency repairs. The contractor is Insituform Technologies of Mt. Vernon.
The county sewer commissioners and the Board of Supervisors Law and Finance Committee have already approved the emergency spending, sending it to the full Board of Supervisors for a final decision Tuesday in Ballston Spa.
In another matter related to aging infrastructure, the board will be asked to authorize an $83,350 contract with Environmental Design Partnership of Clifton Park to do the engineering for an equipment replacement upgrade at the sewer district’s pumping station in Milton. The station, located just south of the Kayaderosseras Creek, is the district’s largest, and hasn’t had major upgrades since it was built in the 1970s. Cooke estimated the total project could cost $1.5 million.
Money for both projects will come from fees paid by users of the sewer system.
